Ricky has long battled with his weight and in 2010 lost a staggering 22lbs, transforming himself from the round-faced comic to a svelte man.

Last year he told People magazine: 'It wasn't so much about the weight, it was more that I was a fat, lazy, out-of-shape slob, to be honest. I didn't eat differently. I probably just stopped having that second meal at 11:30 at night.'

Now he exercises regularly with Jane and in a Tweet earlier this year he said: 'Just explained to Jane that a 50 year old man cross-country running in snow whilst listening to Rocky soundtrack is cool.'

Ricky was recently seen taking a few selfies Kermit the Grog and Miss Piggy at the Hollywood premiere of his new film, Muppets Most Wanted.

Attending the premiere, Ricky displayed a slimmer-than-ever physique in a black suit as he high-kicked and posed his way down the red carpet.

Ricky was seen capturing the evening on his mobile phone leaving his partner Jane, waiting patiently in the wings. She looked stunning in a figure-hugging azure dress.

Muppets Most Wanted sees Kermit in hot water when criminal mastermind Constantine, who looks just like him, lands his doppelganger in jail while he joins the Muppets on their global tour, posing as Kermit.

As well as Ricky, the movie also stars Modern Family's Ty Burrell and comic actress Tina Fey.
